Abstract: An example method performed by a first access and mobility management function (AMF) of a wireless communication system may include establishing a control channel connection with at least two enhanced relays (ERs) through a first base station managed by the first AMF; controlling the at least two ERs to establish a communication channel with a second base station distinct from the first base station through the control channel; and controlling the at least two ERs to transmit data received through the communication channel to a first user equipment (UE).

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. An example method performed by an access and mobility management function (AMF) node in a wireless communication system may include receiving extended access point (EAP) capability related information from an EAP, performing control plane expansion to include the EAP, based on the received EAP capability related information, creating an X2 interface with the AMF node and the EAP based on a number of relevant base stations, instructing the base station to establish an X2 interface with the EAP based on the created X2 interface, and instructing the EAP to establish a connection with a terminal.

Abstract: A method of controlling communication of a plurality of devices belonging to a communication group in a wireless communication system is provided. The method includes requesting generation of the communication group, receiving, from a distributed artificial intelligence entity, information about terminals that are to perform cooperative transmission among the plurality of terminals included in the communication group, identifying, based on the information about the terminals that are to perform the cooperative transmission, the terminals that are to perform the cooperative transmission and modulation methods to be requested for the terminals that are to perform the cooperative transmission, respectively, for the cooperative transmission, and requesting the terminals that are to perform the cooperative transmission, to perform data modulation according to the identified modulation methods, respectively.
